Hey, "Toners" .... I just finished putting a "Jimmy Page - like" home-made harness with 50s style tone wiring into my Epiphone Tribute Plus. I thought that I'd share the experience with the community, I learned a lot through it, perhaps someone here can learn something as well, or get inspired, or something..... Background So, why the term “Jimmy Page – like”? Well, “Jimmy Page – like” to me could mean a wiring scheme using 4 push-pull pots to coil tap, put pups in series, and put them out-of-phase. There are really a lot of "Jimmy Page Wiring" variants on the web, and it’s beyond the scope of this post to discuss what’s good or bad, or even different about them. What I will say is that the version that I decided on, that is based on the Shecter Superock Harness that was published by Steve Ahola, has a big advantage over many similar schemes. That is, when the pickups are in series, there are no dead spots when the pup selector switch is moved to the Treble or Rhythm positions. In some schemes the serial setting only works then the pup selector switch is in the middle position, and the Treble and Rhythm positions are dead. With this scheme the pup selector switch can be anywhere when switching to series, and the neck volume and tone act like master controls when series is switched on. I find this is very useful and cool. After doing a lot of research and reading on the net, I stumbled upon this scheme through a MLP member, Raz59, who had posted his modification of this wiring scheme here. I modified it a little further because I wanted the tone module wired in 50s style, and so I also dumped the treble bleed circuit in Raz59s scheme. Many, many thanks to Raz59 not only for the scheme, but for the numerous discussions that he participated in on several forums from which I learned a whole lot. It really helped me out a lot. Parts I bought all of the pots and caps new instead of reusing stuff out of the T+. For one thing, I now have the original harness that I can drop into any guitar. For another, I was unable to desolder stuff off of the original pots – I suspect lead free solder and my 25W iron couldn’t cope. I prefer linear taper for volume when using 50s wiring, and log taper for tone. I had a pretty hard time trying to find linear taper push-pull pots. Since I’m not a believer in different *brands* of pots having profound influences on tone, and in order to stay metric and to avoid having to enlarge the holes, I stayed with Alpha pots. I found suitable ones at Axesrus, in England. They are the Alpha medium shaft ones – as far as I can tell they are identical with the original T+ tone controls, and Axesrus offers them in both log and linear flavors. I also got 22nF Sprague 192P capacitors from Axesrus. Again, I don’t believe that different *types* or *brands* of caps have a profound influence on tone. These caps are polyester film and foil like the original Mallory 150s that were in the T+, and they have axial leads so they are easy to solder between the pots. And they are Sprague, so they must be good. I also bought some cool cloth and wax wire from Axesrus. This stuff has a profound influence on, well, the way it looks. A little plug for Axesrus – the service was great, I ordered the stuff online on Thursday morning and signed for the package that was delivered here on Saturday morning in Germany. Awesome! Construction I’m going to break the construction down into 4 parts; Signal Path, Signal Ground, Chassis Ground and finally wiring in the pickups and switch. I drew the scheme up in Illustrator putting each of the parts into a different layer so that it is easier to see what is going on. To avoid confusion with the pot DPDT switches: the orientation is such that the part of the switch closest to the center of the pot in the diagrams is the “bottom” of the switch when the pots are mounted on the template and the switches are facing up. I think that this should be pretty obvious. I need to apologize for the quality of the photos. My wife and son were on vacation when I did this, and had taken all of our “good” cameras with them. I was stuck using my cell phone to photograph the stuff. Sorry! The entire circuit is shown below. Note that I am using Gibson colors for the Classic pups in the T+. If using other pups, you need to convert colors accordingly. Also note that I tried to separate signal and chassis ground. Volume controls split neck and bridge pups, respectively. Bridge tone switches out-of-phase. Neck tone switches pups series. Kind of a mess … First thing I did was to build a template out of some fiber board that I had lying around, and to mount the 4 pots to this. Then I started wiring the Signal Path, using some hookup wire (green) for the short wires on the pots, and the cool yellow cloth stuff for the path between the pots. And the caps, of course. Here is the scheme for Signal Path: Next I wired in the Signal Ground, using hook up wire for the short stretches on the pots, and the cool black cloth stuff for the longer ones. Here is the scheme for the Signal Ground: Note that the two long black wires that "end nowhere" are left long enough so that they can be soldered to the jack. Here a photo of Signal Path and Signal Ground wired up. It is now ready to drop into the guitar: A close up: Now to the Chassis Ground. I wanted to avoid soldering to the back of the pots, in order to make it easier to change things should I decide to do so. So I used crimp type M8 lugs in order to slip the pots through these to ground them. I removed the plastic from over the crimp part of the lug and soldered the wires to the lug instead of crimping – again, just in order to make things easier should I decide to change things. Here the scheme: So I cut cool black cloth wires to length using my template for the connections between the lugs, and then soldered the bridge, pups and switch ground wires to these. Note that the connection between jack and switch was already in place on the guitar, I just left this as is. Again, I apologize for the lousy quality of the photo, but I think that you get the idea. The lugs go over the holes for the pots, so that the shafts of the pots can slip through: So now all that’s left to do is to marry the harness with the chassis ground, solder the pickup and switch wires, and to connect the two signal ground wires to the jack. Here is the pickup and switch scheme: Here’s what it looks like all hooked up (can you tell that the vacationers are back?): I was almost shocked that when, after soldering it all together, everything worked perfectly! The guitar is as quiet as it was with the original wiring, so the grounding is good, and everything switches the way that it is supposed to. So, well worth the effort , a really nice upgrade for my Tribute +.
